Find I1, SWR, Zi, given ZL = 100 -j 50 2 with Z. = 150 N, 1= 0.25 A

This is a review question from an old exam:A 50-MHz generator with Zg =50Ω is connected to a load ZL= (50 –j 25). The time average power transferred from the generator into the load is max when Zg=ZL, where ZL is the complex conjugate of ZL. To achieve this condition without changing Zg, the effective load impedance can be modified by adding an open circuited line in series with ZL, as shown in the following figure.  a) If the line’s Z0=100Ω, determine the shortest length of line (in wavelengths) necessary for satisfying the maximum power transfer condition. b)  Determine for the same problem  for a short circuit line in series with ZL.

c) For a transmission line w/characteristic impedance Z0 = 50 W. At some point of the line, a forward wave has the voltage V+ = 10V and backward wave has the voltage V- = 4V. i) Currents of the forward wave and backward wave at that point. ii) Measured voltage and current at that point. d) A transmission line has the following properties: Length, L = 3 m. Characteristic impedance Z0 = 50 W. The load impedance ZL = 100 W. And phase constant b = p/3. Assume the forward voltage at z = 0 is VA =10ejp/4 At z = 3m, calculate: i) Forward voltage and forward current. ii) Backward voltage and backward current. iii) Measured (total) voltage and current across the load

Problem 7

I turned the voltage value of the AC source into Vrms and got magnitude 16.97 & angle 10.Then calculated the impedance of Load A to be [ -9.28 - j23.4 ]. From that, I calculated the complex power of load B to be [ -2.42 + j6.33 ] my power factor calculation I am using inverse tan ( Q/P) , where Q i got -1.91 & P to be 5.559, which I got from my total complex power. If that helps. But I am calculating a negative power factor, so i am curious where I went wrong, Thank you!
